DOOR. Y

SPECIFICATION formingpart vof Letters Patent No. 693,440, ldated February 18, 1902. Application nea May 2,1900. serai No. 15,189. (No man To alt whom t may concern:

Be it lknown that I, CHARLES Il. POPE, ot Brockton, county of Plymouth, State of Massachusetts, have invented an Im provement in Doors, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like. parts. n

This invention relates to doors; and the 0b-l ject of the invention is to provide animproved device of this character so constructed that the employment of a threshold upon its frame or the floor in proximity thereto is not necessary.

The invention includes as one of its features a door and its frame, the door having a bar or strip, means to hold they bar or strip above the lower edge of. said door when the same is open, and means usually mounted upon the frame to throw and maintain the bar or strip down below the lower edge of the door when the same is closed.. In the present case the door has in its lower edge a longitudinal groove adapted to snuglyreceive a bar or strip, and I prefer toemploy a spring to hold said bar or strip in the groove when the door is open, and said bar or strip may be engaged by a projection or stud disposed'in the path of the same upon the frame to force the'same down against the sill orcarpeting or other covering thereon. `By this construction I am enabled to dispense with the usual threshold,

while the bar or strip carried by the door serves when down and while the door is shut to close the opening between the door and floor and exclude cold.

The invention is shown in one convenient embodiment thereof 'in' the accompanying drawings, wherein- Figure 1 is a front view of a portion of` a building having a frame inclosing a door including my improvements. Fig. 2 is a 'sec `tional view of a portionof the door andframe.

Figs. 3 and are transverse seetionstaken in the lines 3,3 and 4 4', respectively, Fig. 2.

Referring to Fig. 1, the numeral indicates Y a door-frame, in which a door, as 6, is hinged.

The door does not extend completely to the door 7 but the space between the two parts when the door is shut is closed by a st-rip or bar which serves to exclude cold from the in terior of an apartment furnished with the door and which strip when the door is open may be seated in a channel or groove in the lower edge of the door.

The door 6 has at its lower end the crosspiece 8, constituting, in effect, a continuation thereof, and which is grooved or channeled,

as vat 9, transversely of the door and completely across the same, the channel being semicircular in cross-section and being adapted to receive the correspondingly-shaped strip or bar 10, which when the door is open is seated in the channel, as indicated by the dotted Awithin the channel 9, and to effect this result I have illustrated a coiled spring, as 14, surrounding the pintle 15 of the hinge 13 and connected, respectively,with.the two members of said hinge. v f

The frame 5 in the present instance isprovided withv means of a suitable nature to engage the swinging strip 10 when the door-is nearly shut, so that on a slight further movement the said strip will be `swung down with its-free edge in contact with ,the flooil 7 or its covering.

rollerbeing supported by the stud or screw 17,"extending throughl a longitudinal slot 18 in a disk or plate 19,` set intoone of the stiles of the door-frame. A recess, as 20, is located back ofthe disk 19 and receives a nut 21," into I have shown a roller 16 as a con- `venientdevice to engage the strip 10, the

which the threaded end of the' stud or screw 17 is tapped. By turning thestud or screw 17 the same can be raised or lowered for the purpose vof vadjusting the roller, andwhen properly positioned the said screw will be turned inthe opposite direction to irmly hold the Asanne in the 'desired position. By making the screw 17 adjustable vertically the roller thereon may be'so adjusted as to swing the strip 10 down diiferentdistances,.according to the thickness of the rug or carpet used on the floor, so that the opening between the door'and the floor may always be closed when the door is shut. The` door is cut away at its rco lower corner, as at 22, so that the roller 16 can engage the adjacent end of the strip 10 in order to swing the same down. As soon as the door is opened and the strip 10 is carried out of contact with the roller 16 the strip will be swung up into the channel 9, into the dottedline position, by the power of the spring 14 and will be there held until the door is shut.

The invention may be modified within the scope of the accompanying claims.

Having described my invention, what I claim, and desire to secu re by Letters Patent, 1s-

l. A door having a groove curvilinear in cross-section in its lower edge, a strip tted to said groove, the inner edge of the strip having a pivotal connection with the door, means to normally hold said strip in place in the groove, one corner of the door being cut away above the strip, a projection on the door-frame adapted to enterI said cut-away portion as the door is closed and contacting with the upper side of the strip to thereby depress the same.

2. A door and its frame, the door having a bar or strip, means to hold the bar or strip above the lower edge of said door when the
